DANIEL G. PUTNAM AND GERLOF BOERSMA, 0F TRAVERSE CITY, MICHIGAN.

ACETYLENE-GAS GENERATOR.

Specification of Letters Patent. Application filed July 8, 1912.

Patented Aug. 25, 1914. Serial No. 708,339.

To all whom it may concern: a

Be it known that we, DANIEL G. PUTNAM and (humor BOERSMA, citizens of the United States, residing at Traverse City, in the county of Grand Traverse and, State of Michigan, have invented certain new and useful Improvements in Acetylene-Gas Generators, of which the following is a specification, reference being had to the accompanying drawings.

This invention comprehends certain new and useful improvements in acetylene gas generators, and has for its primary object a simple and efficient construction of apparatus of this character, the parts of which may be easily assembled and disassembled for the purpose of cleaning or for replenishing the carbid and the water supply.

The invention also has for its object an acetylene gas apparatus designed particularly for use in connection with carbid blocks or bricks which may be conveniently inserted in a vertically elongated suspended frame detachably held within the neckof the generating chamber of the device. And the invention also aims togenerally improve devices of this class so as to render them more useful and commercially desirable.

With these and other objects in View, as will more fully appear as the description proceeds, the invention consists in certain constructions, arrangements and combinations of the parts that we shall hereinafter fully describe and claim.

For a full understanding of the invention, reference is to be had to the following description and accompanying drawing, in which,

Figure 1 is a vertical longitudinal section of our improved acetylene gas apparatus, parts being shown in side elevation, and, Fig. 2 is a detail view of the carbid-holding frame hereinafter specifically described.

Corresponding and like parts are referred to in the following description and designated in the accompanying drawing by like reference characters.

Referring to the drawing, the numeral 1 designates the water reservoir of our improved apparatus, the main body portion of said reservoir being cylindrical, in the present instance, and provided with a tapering or conical lower end 2 which is formed with a discharge opening controlled by a gate or valve 3, underneath which a receptacle 4 is usually placed to receive the sludge or the like discharged through said opening and also to receive the water from an overflow pipe 5 which is connected to the reservoir 1 near the upper end of the latter and which extends down along the side of the reservoir, as clearly illustrated in Fig. 1. The reservoir is supported in a relatively elevated position by means of upwardly converging legs 6. It is formed at its upper end with a filling opening 7 which is flared upwardly and outwardly, as shown.

The gas chamber 8 of our device is formed by a metallic structure which embodies a bell-like lower end 9 formed near its lower edge with apertures 10 and an upwardly tapering elongated neck 11 which is provided intermediate of its ends with a horizontally disposed supporting plate formed with vent openings 13 and of a size to rest upon the upper edge of the reservoir 1 so as to suspend the member forming the gas chamber within the reservoir and spaced from the walls thereof with the upper portion of the neck projecting above the reservoir. Secured to the upper end of the neck 11 is a preferably brass casing 14 which is formed intermediate of its ends and on its inner surface with an annular ledge 15, on which a band 16 is adapted to fit. This band forms the upper end of a carbid-holding frame which also includes vertically elongated bars 17 that are spaced from each other and that are connected at their upper ends to the band 16, the lower ends of said bars being connected by cross bars 18 which directly support a basket 19 of wire mesh. Above the basket 19 are one or more cross bars 20 secured to the bars 17 and adapted to support the carbid 21 which is in the form of blocks or bricks arranged in superposed relation to one another.

Mounted in the casing 14 above the carbid-holding frame is a filtering or drying medium, preferably of a spongy nature, as indicated at 22. The upper end of the casing is preferably closed by a cover 23 which is held in place bya yoke 24 having arms 24' provided with inturned fingers 24 for passing under an external flange 1 1 on the casing 14 and a tensioning screw 25 which is manipulated by a hand wheel 26 and which is tubular and provided at its upper end with a vent cock 27, A pipe 28 leads laterally from the casinglt and is provided with a controlling cock 29, said pipe leading into a filter g cham er 30 from wh ch extends.

the outlet pipe 31 leading to the main and to the burners.

From the foregoing description in connection with the accompanying drawing, the

operation of our improved acetylene gas apparatus will be apparent. In the practical use of the device, the water will act upon the carbid held in the frame which is suspended within the neck 11 and the gas thus formed, will pass up through the sponge or similar material 22 and out through the pipe 28 and filter 30 to the burners, as required.

It will be noted that in our apparatus, the chance of explosions is eliminated, owing to the small amount of gas in the gas chamber. \Vhen the water comes into contact with the lowest carbid gas cake, it forms a charge of gas which presses the water out of the bell and away from the carbid gas cakes. The vent cock is placed at the top of the generator so as to relieve the gas chamber of all air which collects in same when being recharged, The controlling cock 29 is to be closed when the generator is being recharged.

lVhile the accompanying drawing illustrates what we believe to be the preferred embodiment of our invention, it is to be un derstood that the invention is not limited thereto, but that various changes may be made in the construction, arrangement and an overflow pipe connected near lts upper end,

proportions of the parts without departing from the, scope of the invention, as defined in the appended claim.

What we claim is In an acetylene gas generator, the combi nation; of a cylindrical tank having a valve controlled disharge opening in its lower end,

with said tank 40 a closure for the upper end of said tank having a central opening with a downturned flange arranged around it and extending into the" tank, a gas bell removably mounted in said tank and having 5 an upwardly tapering elongated hollow neck extending through the opening in said closure and secured to the flange thereof, a casing secured tot-he upper end of said neck and having an annular ledge on its inner face, a skeleton carbid holder having a band removably engaged with said ledge, said holder extending throughout the length of said neck, and a gas delivery pipe connected with said casing".

In testimony whereof we hereunto affix our signatures in the presence of two witnesses.
